15 GM350T-023 V PACKAGE SPECIFICATION T.B.D 10.0 GENERAL PRECAUTION 10.1 Use Restriction This product is not authorized for use in life supporting systems, aircraft navigation control systems, military systems and any other application where performance failure could be life-threatening or otherwise catastrophic Disassembling or Modification Do not disassemble or modify the module. It may damage sensitive parts inside LCD module, and may cause scratches or dust on the display. GVD does not warrant the module, if customers disassemble or modify the module Breakage of LCD Panel If LCD panel is broken and liquid crystal sp ills out, do not ingest or inhale liquid crystal, and do not contact liquid crystal with skin If liquid crystal contacts mouth or eyes, rinse out with water immediately If liquid crystal contacts skin or cloths, wash it off immediately with alcohol and rinse thoroughly with water Handle carefully with chips of glass that m ay cause injury, when the glass is broken Electric Shock Disconnect power supply before handling LCD module Do not pull or fold the LED or TP cable Do not touch the parts inside LCD modules and the fluorescent LED s connector or cables in order to prevent electric shock Absolute Maximum Ratings and Power Protection Circuit Do not exceed the absolute maximum rating values, such as the supply voltage variation, input voltage variation, variation in parts parameters, environmental temperature, etc., otherwise LCD module may be damaged Please do not leave LCD module in the environment of high humidity and high temperature for a long time It s recommended to employ protection circuit for power supply Operation Do not touch, push or rub the polarizer with anything harder than HB pencil lead Use fingerstalls of soft gloves in order to keep clean display quality, when persons handle the LCD module for incoming inspection or assembly When the surface is dusty, please wipe gently with absorbent cotton or other soft Wipe off saliva or water drops as soon as possible. If saliva or water drops contact Page 15 of 17

16 GM350T-023ATV0.1 with polarizer for a long time, they may causes deformation or color fading When cleaning the adhesives, please use absorbent cotton wetted with a little petroleum benzine or other adequate solvent Mechanism Please mount LCD module by using mounting holes arranged in four corners tightly Static Electricity Protection film must remove very slowly from the surface of LCD module to prevent from electrostatic occurrence Because LCD module use CMOS-IC on circuit board and TFT-LCD panel, it is very weak to electrostatic discharge. Please be careful with electrostatic discharge. Persons who handle the module should be grounded through adequate methods Strong Light Exposure The module shall not be exposed under strong light such as direct sunlight. Otherwise, display characteristics may be changed Disposal When disposing LCD module, obey the local environmental regulations Storage When storing modules as spares for a long time, the following precautions are necessary Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5 and 35 at normal humidity The polarizer surface should not come in contact with any other object. It is recommended that they be stored in the container in which they were shipped Handling Precautions for Protection Film When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ion-blown equipment or in such a condition, etc The protection film is attached to the polarizer with a small amount of glue. Is apt to remain on the polarizer. Please carefully peel off the protection film without rubbing it against the polarizer When the module with protection film attached is stored for a long time, sometimes there remains a very small amount of glue still on the polarizer after the protection film is peeled off You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal-hexane Cautions for Installing and Assembling Bezel edge must be positioned in the area between the Active area and View area. The bezel may press the touch screen and cause activation if the edge touches the active area. A gap of approximately 0.5mm is needed between the bezel and the top electrode. It may cause unexpected activation if the gap is too narrow. There is a tolerance of 0.2 to 0.3mm for the outside dimensions of the touch panel and tail. A gap must be made to absorb the tolerance in the case and connector. Page 16 of 17
